UUU Custom IMX8MM Board

[houssem_chaaban]

Hello all,

This is another update for this issue,

After passing the calibration and stress test and generating ddr3_timing.c file,

I tried to rebuild the u-boot-imx with the new file, and its correctly built,

but when flashing the board with UUU I got a failure, and the log output of minicom is attached.

I found many other people facing this problem with imx6 and 7, and the answers are generally to modify the imx8mm_val.h file under u-boot-imx to set the settings of DDR there too.

Any help?

Thanks again.

Hello,

   According to UUU.pdf, there are Uboot config requirement  ( in order to talk with uuu).

https://github.com/NXPmicro/mfgtools/releases/download/uuu_1.3.102/UUU.pdf 

   Check, if Your U-boot configuration is correct. 

Have a great day,

Yuri

Hello Yuri,

Thank you for your reply. 

We changed the configuration as discribed in UUU.pdf and fastboot is now activated.
Note that we are using USB 1 .
Now we get this error
